Central geospatial database analysis of the quality of road infrastructure data

Abstract

This paper describes the basic logical data model from the central geospatial database (CGD) which is applicable to the structure of a digital topographic map of the largest scale – 1:25,000 made in the Military Geographical Institute (MGI), Belgrade, Serbia. CGD analysis of the road infrastructure quality, done according to the ISO 19157 standard, led to a layering of elements and sub-elements of quality which were analysed separately. ISO 19157 standard defines a procedure of quality assessment which depicts the results of the analysis for each element.
